#163: DAO Policy

 Yvonne-Anne Pignolet:
 In 4.1.3. The authors consider DAO policy to be
 out of scope. However, if basic RPL is applicable for home and
 building automation scenarios then due to P2MP traffic  from roots
 DAOs are required. As in the industrial applicability statement I thus
 recommend a paragraph such as "Nodes send DAO messages to establish
 downward paths from the root to themselves. DAO messages are not
 acknowledged in networks composed of battery operated field devices in
 order to minimize the power consumption overhead associated with path
 discovery.  If devices in LLNs participate in multiple RPL instances
 and DODAGs, it is highly recommended that both the RPLInstance ID and
 the DODAGID be included in the DAO."  If the mailing list consensus is
 that P2P RPL is to be used only, then this Section should state that
 DAO messages are not sent in this case. In addition a comment on
 P2P-DRO  Acknowledgement (P2P-DRO-ACK) would be helpful

 Peter van der Stok:
 Some text to motivate the out of scope of DAO policy can be added.
 For the multiple RPL instances, I prefer to include a reference to other
 texts.
